The 42nd president earned a reported $40 million delivering speeches across the globe since leaving the Oval Office. Clinton earns up to $350,000 a speech, and as much as $10 million a year, making him one of the world's top-earning speakers. (Speeches on behalf of the William J. Clinton Foundation, which focuses on global warming and AIDS in Africa, are given gratis.) Clinton has scaled back on his speaking schedule since wife Hillary announced her bid for president.
